Title: Sound making mechanism for piano like instrument
Inventor: KOBAYASHI EIJI
IPC: G10H3/18
Filed: 1977-11-09
Abstract: PURPOSE: To generate the playing sounds like a cembalo with the sound making mechanism of a piano like instrument by providing a flexible curtain portion of strip shape in a manner to face a hammer corresponding to a key and by attaching a  chord hitting tip to the strip portion.  
     CONSTITUTION: A curtain member 13 is made to depend from a cross frame 12 in a manner to face a chord 11 which is vertically extended under tension for each  sound. When a pedal 17 is depressed, the cross frame 12 is turned down so that the  curtain mamber 12 depends between the chord 11 and a hammer 21. If, under this  condition, the key is operated to drive the hammer 21, this hammer hits the strip  portion 20 of the facing curtain member 13 so that the tip 23 at the leading end hits  the corresponding chord 11 to generate a desired sound. In this instance, the chord  11 is not hit directly by the hammer 21 but by the small tip 23 made of copper or  iron so that the sound generated can resemble that of a cembalo.

Abstract: PURPOSE:To eliminate the nonuniformity in the transverse direction of a gas jet and the local disturbance of the flow rate thereof by decreasing the sectional area of an air tunnel part gradually from a gas introducing port side toward the opposite side thereof. CONSTITUTION:The gas introduced from a communicating hole 13 into a pressure equalizing chamber 15 is introduced along the inner periphery of the pressure equalizing chamber and spreads to flow around in the pressure equalizing chamber 15 by colliding against a sloped part 22 and a perpendicular part 23, etc., to generate vortexes. The gas which is locally lowered in the flow rate and the gas which is not lowered in the flow rate are thereby mingled to uniformize the flow rate. The direction is then changed by a horizontal inside surface 20 of a nozzle lower plate 3 by which the gas is put into a nozzle part 24 where the gas is injected as a jet from a stop nozzle 5 to the surface of a steel strip. Even if, therefore, there is some local nonuniformity in the flow rate of the gas coming from the air tunnel part 6, the flow rate is uniformized in this pressure equalizing chamber 15 and the local disturbance in the flow rate of the jet ejected from the slit nozzle 5 is eliminated.

Title: Data transmission equipment
Inventor: MAEHANA YOSHIO
IPC: H04L25/02
Filed: 1983-07-22
Abstract: PURPOSE:To connect lots of data transmission equipment to one transmission line without being affected with a characteristic impedance of a transmission line by using a constant current circuit for a pulse signal used for turning on/off an output transistor (TR). CONSTITUTION:A pulse signal inputted to a data signal input terminal 8 is clamped to a constant value by a current limit resistor R1 and a constant voltage diode D1. Then the output TR1 is turned on by the pulse signal and a pulse current is generated at an output terminal. In this case, since the circuit constitutes an emitter follower by a feedback resistor R2 and the current flowing is kept to a constant current, a constant current pulse is generated at the output terminal. When a pulse signal is inputted to a data signal input terminal 9, a constant current pulse of opposite polarity is generated at the output terminal similarly.

Title: Device for balancing rotary body
Inventor: HAINTSU REEMAN
IPC: F16F15/32
Filed: 1981-08-27
Abstract: A device for balancing rotating bodies comprising two inertia masses, which are disposed in a cylindrical housing which can be connected to the body to be balanced such as a grinding disc, and which are mutually connected by means of a self-locking worm gear. The inertia masses may be displaced by means of one single switch shaft having four positions in which the two inertia masses can be displaced either countercurrently in both directions or concurrently. When braking is effected by means of a brake knob disposed on the switch shaft, displacement occurs until the indicated imbalance lies within the low, desirable range. The worm shaft and the worm wheel contained in the inertia masses are in engagement with the worm gear of the switch shaft and the housing. An arrangement of this type permits, on the one hand, a simple mechanical construction and operation, and, on the other hand, a large inertia mass, relative to the volume available, with a wide range of adjustment.
